To all whom' it may concern;

lle it known that I,.1.vriueu lillolvor, a citizen of theUnitedStatewresidingat (lil City. in the county ot' Venango and State ofPennsylvania` have invented certain new and usefull Improvement#inFeed-Mixers, of

' which the following is 'i Specification, referaceompanymg draw encebeing had to the ings. 1.

.My invention relates to improvements iu mixers of feed Jfor poultry,live stoel( and the. like', und an object otymy invention is to providea mixer of this elass which will prove simple in construction,lromparatively eheap in inauuiarture, etlieient in use and, which willmix ,the feed thoroughly and imiformly in a minimum of time, whereby agreat :saving `otlabor aiidtiiiie results.

ln the drawings ilhietrating the prineiple of my ilivention and theb'est inode now known to me of applying that principle, Figure t is afront elevation; Fig. l a plan and Fig. 2 an end elevation of my newfeed mixer, Fig. 3 being a view looking in the direction of thearrow inFig. l; Fig. 4 is a side elevation and Fig. 5 a front elevation ot' mynew graiirteedbox; Fig. (i ie a detail showing the greenffeed eonveyerin elevation and Figs. 7, S and 9 are detailsl illustrating theinixiugand-feeding blade and its mounting.

T he ingredients to be mixed are held in a dry State in the feed-boxes athe box or easing bV of whieh is bolted or otherwise fastened` to theveiling of the shed in which the mixer is installed; but these boxes maybe otherwise suitably supported as desired. ltlaeh box 7) is providedwith a slidable door r: and with a movable bottoni d. These, feed-boxesoverhang a conveyor-boxv c in 'whieh iti mounted a shaft which carriestwo helical blades g, h. Flach blade is continuous throughout ithllength, and one blade is a right-handed helix while the other ie-a aleft handed helix. .These blades` constitute helir-.il rouveyers which,force the dry Feed towardl the opening 'in the bottom ot' therouveyer-box r'. The hitter is mounted above the dry-feed trough fi andthe opening i is: dii'eetly over one. end ot' the troi'igh j.

'l`hiia, the material brought to the opening 't by the eonveyer'blailegi falls through the veyer 1 to the trough 7' and is ent and mixedopening together with the nniterial foreed thereto b the iouveyer-hliidelip.' and the mixing oV through the whole length ot the trough j.

' t and 2.

' extension trough r may feed in oie trough j is i-ontinuous- Extendingthrough the latter is a rotary shaft upon which are mounted a series ot'mixing blades m, illustrated in detail in Figs. 7, S and t). Theseblades are .so placed and So inclined upon the shaft that their upperCorners lie in continuons screw.

As the lQhatt c revolves, the blades m beat up and thoroughly mix thedry leed and at the same .time carry it towards the right hand end ofthe trough as viewed in Figs. Further, the green-feed is cauo'ht betweenthe edges,l of the blades and the. si es of the trough, the blades beingadjusted so that they eo-aet with the sides ot the trough to cut thegreen-feed or grass into small bits. The movement ot the material fromend to end of the trough is slow, so that abundant opportunity is givenfor cutting the greenfeed and thoroughly mixing the ingredients. At thisend the. bottom ot the dry feed trough 7' is formed with au opening nwhich is itted with a tunnel pipe n which leads from the dry feed troughj to the wet-feed trough o and through which the dry feed falls into thewet-feed trough o. Through they latter extends a` Shaft 7i upon whichare mounted blades ni so inclined as to drivel the feed from right. toleft, as viewed in Figs. l and 2. ln't-his trough o the feed is wettedwith liquid which flows into the trough through the pipe q. Fitted tothe discharge end of the wet-feed trough 0 is an extensiontrough i'connected therewith by a strapjoint s and mounted upon rollers f. Theextension trough r may be readily disconnected from the wet-feed trough0 audreadily remiived when desired. ln the summer this be placed upon aplatform outsideof the shed; whiley iu the winter it may be removed toallow the doors ot' the shed to he. elosed. Ot rourse, the eon veyf'iu'mounted in the extension trough rais removed with the trough to permitth'vsre- .Quit to be aeroinplished.

In order to mix green with the meal and other ingredients, an ini'linedohute if leads from near the. floor to the dry-feed trough and in thisehute, n is mounted an endless i'onveyer 'n provided with transverseslats or carriers w. The grass or green feed is rarried by the cont'eed.siii-h as grass,

therein by meansl of the blades m.

Miu-h ditlienlty haA heretofore been experii-ueed iu obtaining :inuit'orui iuei-luiuieal the line of a helix or feed of milled rain, suchas meal, Hour and bran. The tee( -box designed b me for this purpose isshown. in Figs. 4 an 5, in which the bottom Z is mounteld free to swingback and forth beneath the box or casing I). The latter is provided oneach side with brackets a: to which are secured one end of a pair ofleaf springs y, the other end of which are secured to hangers z fastenedon each side of the bottom d. From the lower face of the latter projectsears 2 between which rotates a cam 3. The lattci shifts the bott/om dback and forth, the bottom Swingin(r on the yielding leaf-springs y. Asis c eaily indicated in Fie'. 4 the bottom d is slightly ihclined to thehorizontal. The amount of meal fed by t-he'feeder a may be varied byadjustin the position of the door o. The bottom feeds only during itsmovement towards the door c.' and this arrangement of parts and theinclination ot' the bottom permits au accurate control to be exercisedover the amount fed. y

The troughs are suitably supported by the supporting framework 4. .Thefeed-mixing mechanisms are driven from` a shaft 5 upon which is mountedfast a sprocket 6 chainconnected with the sprocket 7 loose upon thi`Shaft p. Keyed upon the latter is a clutchcollar 8 adapted to ci'igagewith the hub oi the loose sprocket-wheel Fast upon the shaft p is asprocket-wheel 9 chain-connected with the loose' sprocket-wheel 1()mounted upon the shaft k, keyed upon which is the clutch-collar 11adapted to engage the hub of the loose sprocket-wheel 10. When theclutch-collar 11 is free from the hub of the latter, the wet feed in thelowermost trough o may be mixed without driving the other feeding andmixing mechanisms, as will now appear. Upon the other end of the shaftlais mounted fast a sprocket-wheel 12 chainconnected with thesprocket-wheel 13, fast upon one end of a shaft 14 which carries abevel-gear 15, which meshes with 'a bevelgear 16 fast upon one end ofthe conveyershaft f. The other end of the latter carries asprocket-wheel 17 chain-connected with the sprocket-wheel 1S mountedfast upon one end of the cam-shaft 19, which carries the. cams 3 (Fig.4). The shaft 14 carries a pulley 20 belt-connected with a pulley 21which drives the shaft 22 upon which is mounted the sprocket 23. Thelatter drives the reen-feed conveyer 'v That portion of the's afts lcand p upon which are mounted the `blades m is referably hollow and throuh it extends tlie shank or stem 24 one end o which is threaded toreceive the sccuring nut 25 and to the other end of which is riveted orotherwise suitably fastened the blades m. The latter rest u on lwashers26, thelower face of whlwh is suitabl shaped te conform to the curvatureof the iollow portion of the shafts l1, p.
